A horizontal axis wind turbine with 24 m diameter blades, running with an average wind velocity of 6.0 m.s^-1, is used for pumping irrigation water. The average air density is 1.23 kg.m^-3. Considering coefficient of power as 0.3, transmission efficiency as 90%, pump efficiency as 60%, acceleration due to gravity as 9.81 m.s^-2 and density of water as 1000 kg.m^-3, the discharge of the pump for a total head of 20 m is ______ L.s^-1. (Rounded off to 2 decimal places)
